In the early 1990s Alberto Moreno, the bass player and founder of the Museo, proposed a new album to Giancarlo Golzi, made of totally new tracks. Merogno, Galifi and Corradi did not join in. In 1999, the band released the concept album EXIT with Marco Balbo (guitar), Marioluca Bariona (keyboards) and Andrea Biancheri (vocals).

In 2002, the Museo accepted the offer from the Finnish magazine "Colossus" to participate to the transposition in rock music of the poem Kalevala. The same band members from the album Exit with a new member, Andrea Pavan (bass), recorded the short suite "Fiore di vendetta".

In 2012, Moreno and Golzi were joined by Galifi, singer of the 1970s' band, guitarists Max Borelli and Sandro Libra, and keyboardist Fabio Meggetto. Moreno worked at mellotron and synthesizer sounds, leaving the bassist role to Andy Senis. This band released the album Zarathustra - Live in studio in October 2012.
April 2013: Museo Rosenbach played for the first time the new concept album Barbarica, in Tokyo, at the "Italian Progressive Festival". From this performance, in March 2014 the band released the live album Live In Tokyo.
